For those of us who have been in the solar industry for decades, to experience the return of battery storage, exemplified by the stratospheric trajectory of Elon Musk's Tesla brand, is something akin to deja vu. If one were doing solar PV back in the off-grid jungle days from the 1970s to the early 2000s, battery storage was required. As grid-tied PV began its ascent in California 2000-2001, more and more manufacturers brought battery-less inverters to market as the demand for grid-tied solar went up. Now batteries are back in force, bigger in capacity, smaller in size, bolder in performance claims, wiser in multiple operating modes, glitzy in form and lower in price. What more can we ask for? Except perhaps the hope that they will work as described and meet the expectations of those early buyers who have imbibed deeply enough of the sales pitch to be willing first adopter...
